Usually, this is the sort of thing that happens when you try to Personalize and/or are using the Control Panel.

Here are some quick fixes you can try to get to the bottom of the COM Surrogate issue.

First, try to understand that this is your computer’s way of trying to tell you that some disaster is afoot. So be cautious and upgrade or uninstall some software that might be causing the malfunction. Check for malware and viruses. If you don’t have an antivirus installed, do it immediately.

There are several software programs that have been accused of causing the dllhost exe error. Among them are:

  • Adobe Photoshop CS3
  • Nero 8
  • Kaspersky Internet Security 2011
  • DivX
  • K-lite

It is possible that these older versions of software are not compatible with your computer. The problem occurs with more frequency on 64-bit systems, rather than 32-bit. The software can be malfunctioning because you need to update the version, and this can cause the problem you are experiencing. However, an easy way of figuring out which app is at fault exists.

Follow this bullet list to find out:

  • Go to Control Panel
  • Select System and Security
  • Then Action Centre
  • Reliability Monitor

By choosing the tab that says “View all problem reports” at the bottom of the window, you will be able to access Problem History. Once there, you need to find the crash report from COM Surrogate and check the entry that says ‘Fault Module Name’. This is where you will find out which program is to blame for the dllhost exe error. By using the fall back system Window 7 has provided for you, you can then uninstall the faulty software and if need be, install it back again in an updated version. This should help with your com surrogate error in Windows 7.

Of course, in this case, you can always update your drivers. A driver that is not up-to-date can cause malfunction, so we suggest using special software, such as Auslogics Driver Updater, to keep track of all the applications you install and the schedule for upgrading them.

If the first suggestion did not help, try the second solution.

This will require some decisions on your part because you will be adjusting some important settings. You need to deactivate your DEP or Data Executing Prevention in an attempt to fix the dllhost error. To do this, you need to find the menu by following this pathway My Computer > Properties > Advanced System settings. In the pop-up window, choose Settings in the Performance section. You will be taken to a window where you can choose the point that says “Turn on DEP for all programs and services except those I select” and check the box that says COM Surrogate. Adding this setting and saving the changes will serve as a dllhost exe com surrogate windows 7 fix for you.
